Abstract

L'INVENTION CONCERNE UN CIRCUIT DE COMMANDE DESTINE A UN ENREGISTREUR BELINOGRAPHIQUE DE SIGNAUX ELECTRIQUES. LE CIRCUIT COMPREND UN ELEMENT DE MEMORISATION C2 DE TENSION, UN ELEMENT DESTINE A CHARGER L'ELEMENT DE MEMORISATION C2, UN COMMUTATEUR QUI, SOUS L'EFFET D'UNE IMPULSION DE COMMANDE, DECHARGE L'ELEMENT DE MEMORISATION APRES UNE CERTAINE ELEVATION DE LA TENSION APPLIQUEE A CE DERNIER ENTRE DEUX IMPULSIONS DE COMMANDE, ET UN ELEMENT QUI DETECTE L'ELEVATION MAXIMALE DE TENSION DE L'ELEMENT DE CHARGE ET QUI REGLE LE DISPOSITIF DE COMMANDE M DE L'ELECTRODE S DE BALAYAGE DE L'ENREGISTREUR AFIN QUE CETTE ELECTRODE S SOIT DEPLACEE A UNE VITESSE PROPORTIONNELLE A LA FREQUENCE DES IMPULSIONS DE COMMANDE. DOMAINE D'APPLICATION : ENREGISTREURS BELINOGRAPHIQUES.THE INVENTION RELATES TO A CONTROL CIRCUIT FOR A BELINOGRAPHIC ELECTRIC SIGNAL RECORDER. THE CIRCUIT INCLUDES A VOLTAGE MEMORIZATION ELEMENT C2, AN ELEMENT INTENDED TO CHARGE THE MEMORIZATION ELEMENT C2, A SWITCH WHICH, UNDER THE EFFECT OF A CONTROL PULSE, DISCHARGES THE MEMORIZATION ELEMENT AFTER A CERTAIN RISE OF THE VOLTAGE APPLIED TO THIS LATTER BETWEEN TWO CONTROL PULSES, AND AN ELEMENT THAT DETECTS THE MAXIMUM VOLTAGE RISE OF THE LOAD ELEMENT AND WHICH ADJUSTS THE CONTROL DEVICE M OF THE RECORDER SCAN ELECTRODE S SO THAT THIS ELECTRODE S IS MOVED AT A SPEED PROPORTIONAL TO THE FREQUENCY OF THE CONTROL PULSES. FIELD OF APPLICATION: BELINOGRAPHIC RECORDERS.
